Title: Improvements in and relating to the operation of electric tramway and railway points
IPC: B61L11/08
Filed: 1936-08-15
Abstract: 470,215. Operating railway and tramway points. REID, W., and LITTLE, W. M. Aug. 15, 1936, No. 22496. [Class 104 (i)] In an electric point - operating system for electric tramways, railways and trolly buses, of the kind embodying a pair of point coils and a skate on the overhead conductor 2, one coil being energized if the collector passes the skate with power off, the other being energized with power on, the circuits of the two point coils 7, 11 are closed by respective contactors 4, 9 energized by the passage of the collector over the skate 3, 12, said circuits being made and broken remote from the skate. If the collector passes with power on, the motor supply is taken through the low resistance coil 1. of the contactor 4 and skate member 3, causing coil 7 to be energized by a circuit independent of the collector and skate, current passing from conductor 2 through wire 5, contactor 4 and wire 6 to coil 7. When the collector reaches the side member 12 of the skate, which is shorter than the member 3, the upper end of the coil 8 of the contactor 9 is raised to the potential of conductor 2 while the lower end is at the same potential through its connection to the wire 6, so that coil 8 remains inactive. If the collector passes with power off, current passes from 2 through 1, 3, collector, 12, 8, 7 to earth, contacts 9 close, and 11 is energized from line 5. The current through 8 will be too small to energize 1 sufficiently to close contacts 4. Overhead frog coils 7a, 11a may be in the circuits of the coils 7, 11. In another form, the lower end of coil 8 is led to a contact engaging contact 4 when coil 1 is inactive, but when the collector passes with the power on, the closing of 4 opens the circuit of 8. In a third form, the lower end of 8 is connected to a contact engaging an insulated contact moving with the contact 4 and providing a connection to earth.
